identifying congruent shapes on a grid
congruent?
yes
no
yes
no
congruent?
yes
no
yes
no

Explanation:

Step1: Analyze top-left shapes

The two rectangles: check side lengths. First rectangle (horizontal) and second (vertical) – same height and width (since grid squares, count units). So congruent (Yes).

Step2: Analyze top-right shapes

Two "L" - shaped figures: check dimensions (lengths of arms, grid units). They match, so congruent (Yes).

Step3: Analyze bottom-left shapes

Two triangles: one small, one large. Different side lengths (grid units), so not congruent (No).

Step4: Analyze bottom-right shapes

Oval and circle: different shapes (oval vs circle), so not congruent (No).

Answer:

Top - left: Yes; Top - right: Yes; Bottom - left: No; Bottom - right: No
